Clearpass NT_STATUS_IO_TIMEOUT

[shartmann]

Dear all,

I wanna prepare Clearpass for Active Directory Authentification. I am following the latest ClearPass_Deployment_Guide.pdf (see attached) and using ClearPass Policy Manager 6.7.1.103729 on C1000V (Trial Version) platform. AD is running on W Server 2008 R2 Standard.

I was able to join the Domain but with an Error "WARNING - Failed to fetch Domain Info for = SD)". But the Computer "CLEARPASS" is created in the AD.
Now to the problem: When I try to authenticate a user using the console "ad auth" it fails with the error "NT_STATUS_IO_TIMEOUT".

I would be very grateful if somebody can help me :)
Best
